Substitution Technique
Once learned, used with its own key (Substitution, X by default), not cast from a release. In a puff of smoke you're gone and a log stands where you were. If someone hurt you in the last 10 seconds and they're within 50 blocks, you reappear a few blocks behind them, facing their back; otherwise somewhere random within 15 blocks. 80 chakra, 15 second cooldown.
